Scenario-adaptive input method editor

ABSTRACT

An input method editor (IME) described herein couples scenarios of the input of the user with specific network services to offer more relevant and richer candidates for higher input productivity. Data relating to a computer application in which the input candidates are to be input and/or context relating to a user-submitted query is collected and analyzed to determine a scenario. The input candidates may include text candidates and rich candidates. The IME may select a scenario-tuned and type specific engine to identify the text candidates and/or rich candidates. The scenario-tuned text candidate engines leverage scenario-tuned language models and lexicons, and the scenario-tuned rich candidate engines leverage scenario-relevant web services, such as image, mapping, and video search, when available and appropriate.

BACKGROUND

An input method editor (IME) is a computer application that assists a user to input texts at a computing device. An IME may provide several input candidates based on received inputs from the user. The inputs and the provided texts may be the same language or different languages.

For example, the user may input one or more initial English characters of a word or phrase and an IME, based on the initial characters, provides one or more complete words or phrases for the user to select a proper one.

For another example, an IME may also assist the user to input non-Latin characters such as Chinese. The user may input Latin characters through a keyboard. The Latin characters may be a spelling of the Chinese characters. The IME returns one or more Chinese characters based on the spelling to the user to select a proper one. As the current keyboard usually only supports inputting Latin characters, the IME is useful for the user to input non-Latin characters.

The input candidate selected by the user can be inserted into various other computer applications, such as a chatting application, a document editing application, a gaming application, etc.

Typically, an IME only provides input candidates in the form of text, and a single source is typically used to identify the input candidates, regardless of the type of application with which the IME is being used.

DETAILED DESCRIPTION

Overview

The disclosed techniques describe an input method editor (IME) that provides input candidates to a user to input into a computer application at least partly based on a scenario of the user input and the queries input by the user. The input candidates may include not only text candidates such as non-Lain characters such as Chinese, Latin characters such as English, but also rich candidates such as multimedia to provide supplemental information to a user to enhance the user experience.

The queries are one or more texts such as characters or symbols input by the user. The queries may represent one or more expressions. For example, a query may be a series of initial characters, an abbreviation, a spelling, and/or a translation of one or more words or phrases. The queries and the expressions represented by the queries, such as words or phrases, may be in the same or different languages. The user may input the queries through a variety of input methods such as a keyboard input, a voice input, and a touch screen input.

The text candidates are the expressions represented by the queries in the form of text. The rich candidates are the expressions represented by the queries in forms other than text such as images and multimedia.

The scenario of the user input may include a scenario of the computer application (e.g., chatting or emailing). The scenario of the user input may also include a context of the user input (e.g., a prior use history of the computing application such as chatting history or contents displayed at the user interface of the computer application such as the user's prior inputs).

There may be many input candidates corresponding to the same query. The ranking of the input candidates may be different in different scenarios of the user input. There is also a different preference of type of candidates in the different scenarios of the user input. In one embodiment, the IME may provide rich candidates in some predefined scenarios of the user input (such as emailing or chatting) and not provide rich candidates in some predefined scenarios of the user input (such as document editing). In another embodiment, the IME may provide rich candidates when the probability that the rich candidates improve user experiences is calculated beyond a predefined threshold.

The IME may determine the type of input candidates to be presented to the user at least partly based on the scenario of the user input. The presented type of input candidates may be text candidates, rich candidates, both, or none.

After determining the scenario of the user input, the type of input candidates, and the queries, the IME selects a proper scenario-specific and type-specific input candidate engine to generate or identify the input candidates. Usually when the input candidates are already available at a database or a network, the proper engine is selected to identify the input candidates. Sometimes, the input candidates are not available at the database or the network, such as a rich candidate showing a map of a user's current location to a desired location. Such rich candidate may be generated by the proper input candidate engine.

The input candidates may also be ranked according to their relevancies to the scenario of the user input. In one example, such ranking may be accomplished by the input candidate engine when it provides the input candidates.

The IME is capable to present both text candidates and rich candidates at a user interface of the IME. For example, the user interface of the IME may include a web browser component capable for HTML5 rendering.

There may be various configurations of the IME to identify the input candidates. In one embodiment, the IME has an engine pool that includes a plurality of preset engines that are each capable to produce scenario-specific text or rich candidates. For example, a preset scenario-tuned text candidate engine, such as a chatting-tuned text candidate engine, may be preset with language models and lexicons tied to the chatting scenario to identify the text candidates suitable in the chatting scenario. The preset scenario-tuned rich candidate engine may use web services to identify or generate the rich candidates. The web services may include, for example, web search, video search, image search, dictionary and encyclopedia search, address book information such as from Microsoft Exchange Server, and/or information from social networking web services.

In another embodiment, one engine may provide both text candidates and rich candidates. For example, the engine may not be preset for the specific scenario but may be adjusted to the specific scenario at real-time after identification of the scenario.

There may also be various configurations for the deployment of the IME. In one embodiment, all components of the IME are located at a client device. In another embodiment, the IME is implemented in a client-server architecture in which some components are located at the client device and some components are located at the remote server relative to the client device. For example, the engine pool may be located at the remote server, and the user interface of the IME may be located at the client device.

FIG. 1 illustrates an example overview 100 of providing scenario-adaptive text and/or rich candidates in an example chatting scenario.

A user 102, via a user interface 104 of an input method editor (IME), inputs one or more objects 106 into a user interface of a computer application 108. Both the user interface 104 of the IME and the user interface of the computer application 108 present at a user interface of a client device 110 at a same time. There may be two or more computer applications (not shown in FIG. 1) opened at the user interface of the client device 110. The user 102 may select the computer application 108 that receives the objects 106 by using a mouse or other inputting methods.

In the example of FIG. 1, the computer application 108 is a chatting application such as Microsoft MSN®. The user interface of the computer application 108 includes two windows, a chatting window 112 and an input window 114. The chatting window 112 displays the objects 106 which are already input into the user interface of the computer application 108. The objects 106 include text and/or rich objects. In the example of FIG. 1, the objects are text objects “Jack: Where are you? Me: I'm home now. Jack: where to go tonight?” Jack is a user name of the opposing party that is chatting with the user 102. Me is a representation of the user 102.

The input window 114 includes input objects 116 that are to be input as the objects into the chatting window 112. In the example of FIG. 1, the input objects 116 are text objects “meet me at.” An input indication 118, represented by “|,” represents an indication to insert the input candidates. The input indication 118 may be, for example, a focus of a mouse to input a next input object 116. The input indication 118 also indicates that the computer application 108 that contains the input indication 118 among many other running computer applications (not shown in FIG. 1) is the one that receives input objects 116 from the IME.

The user 102 may use the user interface 104 of the IME to input the input objects 116. In the example of FIG. 1, the user 102 inputs one or more queries 120 into the user interface 104 of the IME. The IME returns one or more input candidates including one or more text candidates 122 and/or one or more rich candidates 124 at least partly based on the scenario of the user input. The user 102 may then select one or more input candidates from the text candidates 122 and/or rich candidates 124 as the input objects 116.

The query 120 and the text candidates 122 may be any kind of text such as Latin characters (e.g. English), non-Latin characters (e.g. Chinese), symbols, numbers, or a mix of different kinds of texts. The query 120 and the text candidates 122 may be the same language or different languages. For example, the query 120 may represent a series of initial characters, an abbreviation, a spelling, and/or a translation of the text candidates 122.

The rich candidates 124 may include pictures, maps, videos, and/or other forms of representations in addition to texts. The rich candidates 124 may include, for example, pictures, maps, videos, or other forms of representations that provide supplemental information to the user 102 in addition to the text candidates 122.

To assist in determining the input candidates to present, the IME may collect data relating to the scenario of the user input. For example, the scenario of the user input includes the scenario of the computer application 108, i.e. chatting in FIG. 1. The collected data may include, for example, a name of the computer application 108. The scenario of the user may also include a context of the user input such as the objects 106 already displayed on the chatting window 112 of the computer application 108 and the input objects 116, displayed at the input window 114, to be input into the chatting window 112.

The IME may also determine a type of candidates to be presented, i.e., the text candidates 122, the rich candidates 124, both, or none, at least partly based on the scenario of the user input. The IME then selects one or more input candidate engines (not shown in FIG. 1) that are capable to produce scenario-specific and type-specific (i.e. text-specific and/or rich-specific) input candidates.

The selection and ranking of the text candidates 122 and/or the rich candidates 124 may be based on their relevancies to the scenario of the user input. For example, the text candidates 122 or rich candidates 124 with higher relativity with the scenario of the computer application 108 may be ranked with a higher priority to be presented to the user 102.

In the example of FIG. 1, the user interface 104 of the IME includes a query window 126, a text candidate window 128, and/or a rich candidate window 130. The query window 126 receives one or more queries 120 from the user 102 through various inputting techniques, such as a keyboard, a touch screen, or voice inputs.

The query 120 in the example of FIG. 1 is the English characters “Sanlitun,” which represent a spelling of Chinese characters “

.” In another embodiment, the query 120 may directly show the Chinese characters “

.” For instance, the user 102 may speak “Sanlitun” into the client device 110 and the IME directly identifies it as the English spelling of Chinese characters “

” and presents the Chinese characters “

” at the input window 114.

The text candidate window 128 displays the identified text candidates 122. In the example of FIG. 1, the text candidates 122 include a first text candidate “

,” a second text candidate “

village,” a third text candidate “

,” and a fourth text candidate “

.” The text candidates 122 are Chinese characters and a mix of Chinese and English characters corresponding to the query 120. The text candidates 122 include not only the first Chinese text candidate “

,” which is the Chinese expression of the spelling “Sanlitun,” but also other text candidates such as the second text candidates that include more text information such as “

villagelso “

,

” and “

” that may provide more supplemental information to enhance the user experience. The text candidates 122 are identified at least partly based on the scenario of the computer application 108 and the query 120.

The text candidate window 128 may display more text candidates 122 if the user 102 clicks the button 132 for more text candidates 122.

The rich candidate window 130 displays the identified or generated rich candidates 124. In the example of FIG. 1, based on the collected data such as the user's input objects 116 “Meet me at,” the IME determines that the query 120 “Sanlitun” may refer to a location, and the IME may use web services to identify the rich candidate 124 which is a map of “

.” Based on the collected data, the rich candidates 124 may also include a map from the user's current location to “

” (not shown in FIG. 1).

IN one embodiment, the web services are online services, such as Bing® map, that do not require a registration of the user 102 to use. The IMT may directly use the query 120 and/or determined scenario of user input as input parameters to request the web service to return the rich candidates 124. In another embodiment, the web service (not shown in FIG. 1) may be online service that require the registrations of the user 102 to use, such as Facebook®, or requires the registration of the user 102 to provide more functionality based on prior saved user preference, historic data, etc. The IME may pre-store the authentication credentials of the user 102 to log onto and use such web service.

The user 102 may select one or more of the text candidates 122 and/or the rich candidates 124 as the input objects 116 to be inserted at the input indication 118.

Example methods for performing techniques described herein are discussed in detail below. These example methods can be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, functions, and the like that perform particular functions or implement particular abstract data types. The methods can also be practiced in a distributed computing environment where functions are performed by remote processing devices that are linked through a communication network or a communication cloud. In a distributed computing environment, computer executable instructions may be located both in local and remote memories.

The example methods are sometimes illustrated as a collection of blocks in a logical flow graph representing a sequence of operations that can be implemented in hardware, software, firmware, or a combination thereof. The order in which the methods are described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the methods, or alternate methods. Additionally, individual operations may be omitted from the methods without departing from the spirit and scope of the subject matter described herein. In the context of software, the blocks represent computer executable instructions that, when executed by one or more processors, perform the recited operations.

Example Techniques for Generating Input Candidates

FIG. 2 illustrates a flowchart of example method 200 for identifying and/or generating the input candidates. At 202, data relating to the query 120 are collected. For example, if the user 102 inputs one or more characters “Sanlitun” into the query window 126. The “Sanlitun” is identified as a query 120 to be collected to search for matching text candidates 122 and/or rich candidates 124.

At 204, data relating to a scenario of the user input are collected. In various embodiments, the IME may collect different data relating to the scenario of the user input from one or more sources. For example, the IME may identify the computer application 108 that receives the input objects 116 among multiple computer applications opened at the interface of the client device 110. The IME may, for example, check the input indication 118 to identify the computer application 108.

After identification of the computer application 108 to receive the input objects 116, the IME may collect data relating to the scenario of the computer application 108, such as the name and version of the computer application 108. In the example of FIG. 1, the name of the computer application 108 is Microsoft MSN®, and the version of the computer application 106 is MSN Messenger 7.5 for Windows XP®.

The IME may also capture current contents displayed at the user interface of the computer application 108, such as the objects 106 in the chatting window 112 and the input objects 116 at the input window 114. For example, the IME may use screen pixel information based on visual understanding techniques such as OCR to identify the displayed contents. In the example of FIG. 1, the IME may capture the chatting displayed at the interface of the computer application 108, such as “Jack, where are you? Me: I am home now. Jack: where to go tonight?”

The IME may also collect a previous user history of using the computer application 108. Such user history may be stored locally or remotely, and may be helpful to analyze the context of the recent inputs. For example, when the computer application 108 is Microsoft MSN®, the user history may be a chatting history of the user.

At 206, the collected data are analyzed to determine the scenario of the user input. There are various techniques to determine the scenario. For example, the name of the computer application may be compared to a list of scenarios. The list of scenarios stores the corresponding relationships between the computer applications and scenarios. For instance, the list may indicate that the computer application Microsoft MSN® corresponds to the scenario of chatting, and the computer application Microsoft Word® corresponds to the scenario of document editing. Such list of scenarios may be updated periodically to include the corresponding relationships with new computer applications and to update the corresponding relationships.

The contents displayed at the user interface of the computer application 108 and the previous user history may also be used to identify the scenario of the computer application 108. For example, based on the context of the contents displayed at the user interface of the computer application 108, the IME may determine that it is a scenario of chatting based on a pattern of chatting identified from the objects 106 in the chatting window 112.

At 208, the type of input candidates to search for is determined. The IME may determine whether the text candidates 122, the rich candidates 124, both, or none should be searched.

In one embodiment, the types of input candidates may be determined based on the query and data relating to the scenario of the user input. For example, the scenario of the computer application may be determined as a short message service (SMS). As the SMS only supports text, the IME would not request and display the rich candidates 124. The IME may also check whether the computer application supports multimedia messaging service (MMS), and may transform the rich candidates 124 into the form of images when their original forms are videos.

For another example, the IME may further determine what kind of rich candidates 124 are to be searched and presented. In the example of FIG. 1, after analyzing the context of the dialog between the user 102 and the opposing party, the IME may conclude that the query 120 “Sanlitun” refers to a location. Thus the rich candidates 124 may refer to a map showing the location. In another example, after analyzing the context of the dialog between the user 102 and the opposing party in the computer application, the IME may determine that the user 102 and the opposing party are discussing music. When the user 102 enters a query such as “Michael Jackson,” the rich candidates 124 may show some famous songs of Michael Jackson such as “Beat it!”

At 210, the input candidates are searched at least partly based on the analyzed scenario of user input, the queries, and the determined type of input candidate.

Different techniques may be used in searching for the text candidates and/or the rich candidates. For example, one input candidate engine may be configured to search both text candidates 122 and rich candidates 124. For another example, the input candidate engine may adjust its language model and lexicon and/or web search service according to the specific scenario at real-time after the identification of the scenario is completed.

For yet another example, there may be a plurality of input candidate engines that form an engine pool. Each input candidate engine is preset for a specific scenario such as chatting, document editing, gaming, and for a specific type of candidates, i.e. text candidates or rich candidates.

At 212, the input candidates are returned and displayed at the user interface 104 of the input method editor. In one example, the user interface 104 of the IME presents the text candidate window 128 and/or the rich candidate window 130 when there are corresponding text candidates 122 and/or rich candidates 124. In another example, the user interface 104 of the IME may present the text candidate window 128 and the rich candidate window 130 even when there are no corresponding text candidates 122 and rich candidates 124.

When the input candidates include rich candidates 124, the IME may use various techniques to present the rich candidates 124 at the user interface 104 of the IME. For example, the rich candidates 124 may be rendered within an embedded web browser component capable of Hypertext Markup Language (HTML) rendering using JavaScript and CSS technologies. Specifically version 5 of HTML (referred to as HTML5) may be supported by this component in order to leverage advanced rendering functionality. The IME may communicate with the browser to display results by generating an HTML string in memory and loading it in the browser. The IME may retrieve the selected rich candidates 124 by catching browser events, such as navigation, and parsing out the rich candidate payload information from the navigation event arguments.

In one or more operating systems, the IME may be implemented in such a way as to not have focus. The focus indicates that a graphical user interface (GUI), such as the user interface 104 of the IME, is currently selected to receive inputs. This may present an issue when interacting with the web browser component and the rich candidates it presents. For example, an “out of process” window may be utilized to render rich candidates. In the Windows® operating systems, an “out of process” window may be invoked as an out of process Component Object Model (COM) server. To present this window properly, interfaces for communication between the user interface 104 of the IME and the COM object may be established to coordinate layout and positioning.

For another example, a particular rich candidate engine may need to have computer-executable instructions or codes registered on the client device 110 to be effective in optimally inserting the rich candidates 124 into the user interface 104 of IME. Some application program interface (API) to communicate with the rich candidate engine may be implemented.

FIG. 3 illustrates an example search engine pool 300 that includes a plurality of input candidate engines. Each input candidate engine is already pre-configured or tuned for a specific scenario and for a specific type of candidates, i.e. text candidates or rich candidates. For example, the search engine pool 300 includes a first scenario-tuned text candidate engine 302(1), . . . , and a N-th scenario-tuned text candidate engine 302(N). The N can be any integer.

The text candidate engine, such as the N-th scenario-tuned text candidate engine 302(N) may include a decoder 304(N), a scenario-tuned language model 306(N), and a scenario-tuned lexicon 308(N). The decoder 304(N) includes one or more algorithms that process the scenario-tuned language model 306(N) and the scenario-tuned lexicon 308(N). In one example, the decoder 304(N) may be optimized for different text candidate engines, i.e. the decoder 304(1) and the decoder 308(N) may be different. In another example, the decoder 304(N) is the same or substantially the same for some or all text candidate engines, i.e. the decoder 304(1) and the decoder 304(N) may be the same or substantially the same.

The scenario-tuned language model 306(N) and the scenario-tuned lexicon 308(N) are components that are trained on data typically seen in the target scenario, i.e. the N-th scenario. In other words, different scenario-tuned text candidate engines may have different scenario-tuned language models and/or scenario-tuned lexicon.

In one embodiment, the lexicon may be a set of expressions such as words, phrases, and/or sentences. In another embodiment, the lexicon may be a set of expressions, such as words, phrases, and/or sentences, assigned with rankings/probabilities of how they are commonly used. The language model assigns a probability to the sequence of the expressions by means of a probability distribution. If the expressions in the lexicon are already assigned with rankings/probabilities, the language model may adjust the rankings/probabilities according to the scenario. The scenario-tuned language models and scenario-tuned lexicon are pre-configured according to the scenario of the user input. For instance, expressions in the chatting scenario are much more informal than those in the document editing-scenario. A chatting-tuned language lexicon may have more informal expressions compared with a document editing-tuned lexicon, and a chatting-tuned language model ranks the informal expressions higher than those in the document editing-tuned language model.

The engine pool 300 may also include a plurality of rich candidate engines. Each of the rich candidate engines is tuned to a specific scenario, such as chatting, document editing, and gaming. Each of the rich candidate engines may also be a web service tuned for a specific scenario.

In the example of FIG. 3, the scenario-tuned rich candidate engine 310 may, for example, utilize one or more web services, such as search engines, to return the rich candidates. The controller 312 may select a web service depending on the scenario. In an example implementation, there may be a first web service for a first scenario 314(1), . . . , and a M-th web service for a M-th scenario. M can be any integer and may or may not be the same as N.

Some web services may rely on account information of the user 102 that the user 102 registers with such web services. For example, the engine pool 300 may allow remote calls to be made securely and potentially on behalf of the user 102 to use authentication techniques to connect with user services like micro blogging accounts.

Alternatively, some web services may not rely on whether the user has registered services. For example, such services may include web search related services, such as image search, mapping services, and video search.

The search engine pool 300 may add, delete, or modify a text candidate engine or rich candidate engine corresponding to a new or an existing scenario. The isolation of different engines also helps to improve the flexibility and robustness of the search engine pool 300 in which failure or removal of one input candidate engine would not affect another.

In one embodiment, the engine pool 300 may also include a default text candidate engine, such as the N-th scenario text candidate engine 302(N) and a default rich candidate engine, such as web service for M-th scenario 314(M) to provide input candidates when the scenario of the computer application cannot be determined or there is no input candidate engine in the engine pool 300 tuned for the scenario of the computer application.

When an appropriate scenario-specific engine cannot be found, the default engine for a particular request type, such as the N-th scenario text candidate engine 302(N) and web service for M-th scenario 314(M) may be selected to identify the input candidates.

In one example, the default text candidate engine or the default rich candidate engine is not pre-configured to a specific scenario. For instance, the default rich candidate engine is tuned to a general scenario such as using the search engine such as Bing® service to return rich candidates based on the query without limiting the scenario of the user input.

In another example, the default text candidate engine or the default rich candidate engine may be a designated text candidate engine tuned for a specific scenario, such as document-editing, and a designated rich candidate engine tuned for a specific scenario, such as chatting. If the scenario of the computer application cannot be determined, then such default designated text candidate engine or rich candidate engine is selected.

In another embodiment, when the types of input candidates to be searched cannot be determined, the IME may only choose the default text candidate engine to identify the text candidates without using any rich candidate engine. This may avoid generating unnecessary rich candidates that distract the attention of the user 102 and lengthening the time to identify input candidates.

In yet another embodiment, when an appropriate scenario-specific engine cannot be found, the IME may return an error message to display on the user interface 104 of the IME to indicate to the user 102 that no input candidates can be offered.

FIG. 4 illustrates a flowchart for an example method 400 for identifying text candidates.

Referring back to 208, it is determined that the type of input candidates to be searched is text candidates.

At 402, a message including the user-submitted query, the request type of text candidates, and the scenario of user input is received by the IME. For example, the scenario of user input and other information may be in the form of a text string.

At 404, a selection component of the IME determines whether there is a scenario-tuned text candidate engine in the engine pool that corresponds to the scenario indicated in the request.

At 406, in an event that the result of the determination is positive, the message is transmitted to the scenario-tuned text candidate engine to identify the text candidates.

At 408, in an event that the result of the determination is negative, an error message is generated and may be presented at the user interface 104 of the IME. Alternatively, the message may be transmitted to a default scenario-tuned text candidate engine to identify the text candidates.

FIG. 5 illustrates a flowchart for an example method 500 for generating rich candidates. Referring back to 208, it is determined that the type of input candidates to be searched is rich candidates 124. At 502, a message including the user submitted query, the request type of text candidates, and the determined scenario of user input is received by the IME. For example, the scenario of user input and other information may be in the form of a text string.

At 504, a selection component of the IME determines whether there is a scenario-tuned rich candidate engine in the engine pool that corresponds to the scenario.

At 506, in an event that the result of the determination is positive, the message is transmitted to the scenario-tuned rich candidate engine such as a web service to identify the rich candidates. For example, the scenario-tuned rich candidate engine may be preset with a plurality of parameters tuned to the scenario. In a chatting scenario, for example, the query is “haha,” which represents the sound of a laugh. The chatting-tuned rich candidate engine may, for example, search images and multimedia by using the query “haha” and limiting the type to cartoon images and multimedia.

At 508, an HTML string containing the rich candidates is identified or generated. The HTML string may, for example, srefer to JavaScript or cascading style sheets (CSS) resources files locally stored at the client device 110. The string may also refer to external resources like photos or video files available over a network such as the internet or intranet.

At 510, the HTML string is loaded into memory of the client device 110 to present at the user interface 104 of the IME. For example, an embedded web browser may be used for the rich candidate window.

At 512, in an event that the result of the determination at 504 is negative, the selection component of the IME also determines whether there exists a default text candidate engine and/or a default rich candidate engine. At 514, in an event that the result of the determination at 512 is positive, the selection component of the IME transmits the message to the default text candidate engine and/or the default rich candidate engine. The operations continue to 508.

At 516, in an event that the result of the determination at 512 is negative, an error message is generated and may be presented at the user interface 104 of the IME.

Example Application Scenarios

The techniques below are described in the context of different scenarios. However, the techniques described herein are not limited to implementation of the specific described scenarios. Unless specified otherwise, one of ordinary skill in the art can apply or extend the techniques described in one scenario to another.

FIG. 6A and FIG. 6B illustrate how text candidates may be determined differently for different scenarios when query 602 are same.

In both FIG. 6A and FIG. 6B, the query 602 are the same “fz,” which is an abbreviated spelling corresponding to numerous Chinese words.

In FIG. 6A, the computer application 604 is determined as a document editing application. For example, the name of the computer application 604 is identified to be Microsoft Word®, and, accordingly, a “document editing” scenario may be determined according to the name. In FIG. 6A, the user interface 606 of the IME is placed on top of the user interface of the computer application 604.

In view of the scenario of document editing, a text candidate engine tuned to the document editing scenario is selected. The text candidates 608 are identified at least partly based on the scenario and the query 602.

In the example of FIG. 6A, the text candidates 608 include three Chinese terms. As the scenario of document editing requires more formal language style, these Chinese terms are more formal than those in FIG. 6B which is described below.

The first Chinese term,

, means “complicated” in English. The second Chinese term,

, means “nonetheless” in English. The third Chinese term,

, means “house” in English. The user 102 may select more Chinese terms by clicking the button 610.

Based on the scenario of the user input including the context of the user input, i.e. input objects 612 already presented at the user interface of the computer application 604, the Chinese terms are ranked according to their relevancies to the scenario. The Chinese term,

, which means “complicated” in English, ranks first in FIG. 6A.

In FIG. 6B, the computer application 614 is determined as a chatting application. For example, the name of the computer application 614 is identified to be Microsoft MSN®, and, accordingly, a “chatting” scenario may be determined according to the name. In FIG. 6B, the user interface 616 of the IME is placed on top of the user interface of the computer application 614.

In view of the scenario of chatting at least partly based on the name of the computer application 614, a chat-tuned text candidate engine that is tuned to the chatting scenario is selected. The text candidates 618 are identified at least partly based on the chatting scenario and the query 602.

In the example of FIG. 6B, the text candidates 618 include three Chinese terms. As the scenario of chatting typically employs less formal language style and more oral language style, these Chinese terms are less formal.

The first Chinese term,

, means “horrible” in English. The second Chinese term,

, means “capsulation” in English. The third Chinese term,

means “crazy guy” in English. The user 102 may select more Chinese terms by clicking the button 620.

Based on the determined scenario of the user input including the context of the user input, i.e. the input objects 622 already presented at the user interface of the computer application 614, the Chinese terms are ranked according to their relativities to the scenario. The Chinese term,

, which means “horrible” in English ranks first in FIG. 6B.

Thus, as illustrated in FIGS. 6A and 6B, using scenario-tuned text candidate engines can result in contextually applicable text candidates based on a determined scenario from which a user-submitted query is received.

FIG. 7 illustrates providing rich candidates based on varying degrees of information in the scenario of the user input.

To generate or identify the rich candidates 702 like the map in FIG. 7, context of the scenario of the user input may be used with varying degrees of specificity. For example, in the example of FIG. 7, the input object 704 shows that the user 102 only inputs “Let's meet at Sanlitun.” Accordingly, the map may only show the regional map information around the location Sanlitun.

However, the rich candidates 702 may further include another map (not shown in FIG. 7) that shows a direction from the address of the user 102 or the address of the opposing party to the location Sanlitun. For example, the objects already displayed on the chatting window or the input objects at the input window may include information such as “I′m at location X” and “Meet me at location Sanlitun.” Such context could be used for producing a directional map. For example, a map candidate would not just be of point Y such as the location of Sanlitun, but be a map where one or more paths from X to Sanlitun are shown.

The rich candidate engine (not shown in FIG. 7) may use web mapping services, such as those found on web search engines like Microsoft Bing® to generate or identify the rich candidates 702. The scenario of the user input such as the address information and the query 708 “Sanlitun” are relevant parameters to be used by such a web service.

FIG. 8 illustrates providing rich candidates in a form of images.

In the example of FIG. 8, the computer application 802 is a chatting application. To trigger a rich candidate engine to generate or identify the rich candidate such as image candidates, the scenario of the user input is important. For example, for the query 806 “haha,” the chat-tuned text candidate engine identifies text candidates 808 including two terms, i.e. “

” in Chinese, which means “smile” in English, and “haha” in English which also means the sound of a laugh.

The selection component of the IME may choose the chat-tuned rich candidate engine to identify the rich candidates 804 based on the fact that the scenario is chatting. Image candidates are appropriate in an informal chatting scenario; however in another scenario like formal document editing, it may be preset as inappropriate in some embodiments. Therefore, for a different scenario, the type of input candidate may not include rich candidates, and thus the rich candidates would not be searched and presented.

FIG. 9 illustrates providing rich candidates in a form of videos.

To trigger a rich candidate engine to generate or identify rich candidates such as video candidates, the scenario of the user input is important. For example, if the queries match a movie name and the scenario is chatting, the IME may determine a video rich candidate is proper. However when the user is authoring a formal document, such as a high school research report on a film maker's work, an embedded video would not be warranted and the video rich candidate may not be presented.

In the example of FIG. 9, the computer application 902 is a chatting application. The queries 904 are “bian'xing'jin'gang'yu'gao'p,” which are a spelling of the Chinese phrase “

,” which means “preview of Transformer” in English. The text candidates 906 include two Chinese terms “

” and “

” which are ranked according to their relativity to the queries. The Chinese term “

” is ranked first while the Chinese term “

” is ranked second.

The chat-tuned rich candidate engine may use web video search services, such as those found on web search engines like Microsoft Bing®, to search for videos relating to the “

” to enhance the richness of the user's input to aid in productivity. The rich candidates 908 include three videos from different websites such as “Ku6” and “tudou,” and each have different parameters such as different video lengths.

Depending on the capability of the chat application 902, the integration could include embedding the rich candidates 906 in the form of video in varying degrees of fidelity into the chat stream. For example, if the chat application 902 does not allow for video itself to be directly embedded, but an animated gif is supported, the IME could use a web service to convert the video to an animated image such as an animated GIF format to provide an optimal integration. Another fallback is a still image of the video, such as the one found in the thumbnail representation on video search engines. The final fall back would be a hyperlink alone, pointing to the video online.

FIG. 10 illustrates providing rich candidates in a form of address book entries.

In the example of FIG. 10, the computer application 1002 is an email application such as Microsoft Outlook®. When the user 102 inputs the query 1004 “Wangli,” the returned text candidates 1006 include five Chinese terms corresponding to the spelling of “Wangli.”

The rich candidates 1008 include detailed contact information of a person named “Wangli Chao.” The rich candidate engine tuned to the mail scenario may use an address book service, which may be available, for example, through a local mail service application such as Microsoft Outlook® or a remote address book service, such as Microsoft Exchange® server.

FIG. 11 illustrates providing rich candidates in a form of address book entries from multiple sources. This assists the user 102 to quickly input contact information of a person from multiple address book entries by using the name of the person as the query.

The computing application 1102 is an email application. If the user 102 has subscribed to multiple address book services, the address book services will be ranked according to their relevancies to the current scenario. In the example of FIG. 11, the available services are listed at the bottom of the rich candidate window 1102. The item 1104 represents an address book service from Microsoft Outlook®. The item 1106 represents an address book service from a micro-blog service, such as Twitter®. The item 1108 represents an address book service from a social network service, such as Facebook®.

The item 1104 is ranked first as it is more appropriate to the current scenario compared to the items 1106 and 1108. For example, it is determined that the queries 1104 match the name of an address book entry in Microsoft Outlook® and the computer application 1102 is Microsoft Outlook® and the source of Microsoft Outlook® ranks first based on the scenario of the computer application 1102.

The rich candidate view presents address book entries from multiple sources in one user interface of the IME and is easier for the user 102 to switch between different sources to select a desired address book entry.

FIG. 12 illustrates rich candidates linked with applications.

In the example of FIG. 12, the computer application 1202 is an email application and the rich candidates 1204 include an address book entry. A separate application 1206, distinct from the IME and the computer application 1202 that receives input objects, such as Microsoft Lync® can be launched, for example, by clicking over the contact's photo 1208 included in the rich candidates 1204. This would further enable other applications, such as calling by Skype® and calling a phone number if the user clicks corresponding items 1206 and 1208 respectively.

The user 102 thus needs not to open the application 1206 in another session to conduct operations. Such operations to launch the application 1206 can all be done through and within the user interface of the IME.

FIG. 13 illustrates scenario-adapted integration of rich candidates.

A user-selected rich candidate 1302 is inserted in an optimal format under the scenario of the computer application 1304. The computer application 1304 is an email application. In the case of inserting an email address, if the computer application 1304 supports email hyperlinks, the rich candidate 1302 would be specially formatted as an email hyperlink according to the format supported by the computer application 1304.

FIG. 14 illustrates rich candidates in an example social network scenario.

The social networking applications such as Facebook® or social micro-blogging services like Twitter® or Sina Weibo® are currently very popular. The IME may receive and store the authentication credentials, such as user names and passwords, for the services the user 102 likes to use, such as the social network applications, through the input of the user 102. The IME would then be able to provide social networking relevant rich candidate results in specific scenarios.

In the example of FIG. 14, the computer application 1402 is a micro blogging website such as Sina Weibo®. In the scenario of entering a user name for a microblog post, the user first enters input object 1404 “please come to see @.” The symbol “@” refers to a user name or nickname in the context of the computer application 1402. The IME may first use the stored authentication credential to access account and contact information of the user 102 stored at the computer application 1402 either at a local client device or at a remote server.

The IME then suggests user names based on a search of a query 1406 from the accessed contract information of the user 102 at the computer application 1402.

Text candidates 1408 shows three Chinese terms corresponding to the English spelling “Huang” as the query 1406. Rich candidates 1410 show three user names, which are “Huang Xianjun,” “Huang Yi,” and “Huang Yu.”

The rich candidates 1410 are retrieved from the accessed account information and contract information of the user 102 stored at the computer application 1402. The rich candidates 1410 represent full names of users by using the query 1406 and may include useful reference information such as the “status” information of the corresponding users and picture.

An Exemplary Computing System

There may be various configurations of the IME. In one embodiment, as shown in FIG. 15A, all components of the IME 1502 are located at the client device 110.

FIG. 15A illustrates an exemplary embodiment of the IME 1502, which can be used to implement the techniques described herein, and which may be representative, in whole or in part, of elements described herein.

The client device 110 may, but need not, be used to implement the techniques described herein. The client device 110 is only one example and is not intended to suggest any limitation as to the scope of use or functionality of the computer and network architectures.

Memory 1506 may include volatile memory, non-volatile memory, removable memory, non-removable memory, and/or a combination of any of the foregoing. Generally, memory 1506 contains computer executable instructions that are accessible and executable by the one or more processors 1504.

The memory 1506 is an example of computer-readable media. Computer-readable media includes at least two types of computer-readable media, namely computer storage media and communications media.

Computer storage media includes volatile and non-volatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules, or other data. Computer storage media includes, but is not limited to, phase change memory (PRAM), static random-access memory (SRAM), dynamic random-access memory (DRAM), other types of random-access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, compact disk read-only memory (CD-ROM), digital versatile disks (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information for access by a computing device.

In contrast, communication media may embody computer readable instructions, data structures, program modules, or other data in a modulated data signal, such as a carrier wave, or other transmission mechanism. As defined herein, computer storage media does not include communication media.

Any number of program modules, applications, or components can be stored in the memory 1506, including by way of example, an operating system 1508, one or more computer applications such as the input method editor 1502, a chatting application 1510, a document-editing application 1512, a gaming application 1514, and an email application 1516, other program modules, program data, computer executable instructions.

The input method editor 1502 includes a user interface 1518, a collection component 1520, an analysis component 1522, a selection component 1524, an engine pool 1526, and a presentation component 1528.

The user interface 1518 receives queries from the user 102 and presents the returned text candidates and/or rich candidates. The collection component 1520 collects data relating to the scenario of the user input and the queries. The analysis component 1522 analyzes the collected data and determines a type of input candidates to request and the scenario of the user input. The selection component 1524 selects a scenario-tuned and type-specific input candidate engine from the engine pool 1526 based on the queries, the scenario of the user input, and the determined type of input candidates.

The engine pool 1526 includes a plurality of input candidate engines, each of which may be designed for a specific type and scenario. The engine pool 1526 may also include a default text candidate engine and/or a default rich candidate engine to generate and/or identify input candidates when the scenario cannot be determined or there is no input candidate engine tuned to the specific type and scenario.

The presentation component 1528 displays the returned input candidates including the text candidates and/or rich candidates at the user interface 1518.

Some modules of the IME 1502 may be implemented as separate systems and their processing results can be used by the IME 1502.

For the sake of convenient description, the above IME is functionally divided into various modules which are separately described. When implementing the disclosed system, the functions of various modules may be implemented in one or more instances of software and/or hardware.

The IME 1502 may be used in an environment or in a configuration of universal or specialized computer systems. Examples include a personal computer, a server computer, a handheld device or a portable device, a tablet device, a multi-processor system, a microprocessor-based system, a set-up box, a programmable customer electronic device, a network PC, and a distributed computing environment including any system or device above.

In the distributed computing environment, a task is executed by remote processing devices which are connected through a communication network. In the distributed computing environment, the modules may be located in storage media (which include data storage devices) of local and remote computers.

In another embodiment, as shown in FIG. 15B, the components of the IME 1502 are located at both the client device 110 and a server 1530 to provide functionality.

In the example of FIG. 15B, the IME 1502 resides at both the client device 110 and the server 1530, separate from the client device 110. The client device 110 and the server 1530 may communicate through a network 1532. The network 1532 may be the internet or an intranet, and may include wired and wireless networks. For brevity, FIG. 15B does not show the operating system 1508 and the various computer applications as shown in FIG. 15A. It is appreciated that the various computer applications such as the chatting application 1510, document-editing application 1512, the gaming application 1514 and the email application 1516 may also use a client-server architecture or a web service.

In the example of FIG. 15B, the user interface 1518, the collection component 1520, the analysis component 1522, and the presentation component 1528 reside at the client device 110. The selection component 1524 and the engine pool 1526 are located at the server 1530.

There may be other configurations of an IME in the client-server architecture. In another example the selection component 1524 may be located at the client device 110. In yet another example, the components that are located at the client device 110 and the server 1530 may be different from those in FIG. 15B. For example, the engine pool 1526 may reside at another independent server (not shown) separate from the server 1530 that hosts the selection component 1524.
